ATOMIZER Filed Sept. 13 1929 Patented Sept. 6, 1932 PATENT OFFICE 1EDWIN C. YOST, OF WINCHESTER, VIRGINIA A'roMIzEia Application filed septmb er 13,1929. Serial No. 392,460.

'This invention relates to atomizers, and has particular reference toatomizers of spray forming type, in which the liquid to be sprayed isdrawn from the receptacle through a suitable conduit by the vacuumaction of a stream of air on the discharge end of such conduit and withwhich the liquid mingles and is discharged in the form of a spray orvapor. 1 The primary object of the invention is to provide an apparatusof this character, which is simple yet thoroughly reliable, practicaland efficient in operation, easily kept in order and handled, consistentwith comparatively few parts and is particularly adapted for use in thetreatment of widely prevalent diseases of the mucous membranes ofthemouth.

Other objects and advantages of the invention will become apparentduring a study of the following description, taken in con nection withthe accompanying drawing, wherein: I

Figure 1 is alongitudinal vertical sectional view taken through theapparatus, the bulb of the atomizer being shown in elevation,

' Figure 2 is a topplan view of the outlet or jet end of the spray tube,

Figure 3 is a vertical transverse sectional Figure 1,

Figure 4 is a similar view taken substantially on line 44 of Figure 1,

Figure 5 is an end view of the spray tube. Referring more in detail tothe drawing, it will be seen that my improved atomizer comprises aliquid container designated generally by the reference character 5, andit is preferable that the liquid container be 7 formed of glass or likematerial.

The container 5 is provided with a reduced filler neck 6 surrounded byan externally grooved flanged ring 7 formed integral with the neck,which ring acts in the capacity of C a packing ring.

end thereof on the cap 8, and at said one end the tube 9 is providedwith a laterally-exview taken substantially on the line 3-3 oftendingtube 10 which tube 10 extends at substantially right angles to the tube9.;

The tube 10. is adapted to extend through a suitable opening ll formedin the cap 8 to extend down into the liquid container 5, At said oneend, the tube 9 is also provided with a laterally extending tube 12,which tube 12 is of a diameterless' than the diameter of the tube 10 andthis tube 12 is curved towardits free end as at 13; V

The tube 12 may be termed as an air conducting tube, and communicateswith said one end of the tube 9 adjacent the tube 10, said tube 12 isalso adaptedito extend through i the opening 11 in the cap 8 to extenddown? wa-rdly into the fluid container 5.

At its outlet end the tube 12 terminates ad jacent the lower end of thetube 10 as clearly shown to advantage in Figure 1. The tube 9 may havesaid one end portion either formed integrally with the cap 8 or securedthereto in any well known manner such as welding or any other Waypreferable or may be detachably secured to the cap as may be desired,and as is obvious. I

At that end which rests upon the cap 8, the tube 9 is provided with asuitable bulb 14, while at that end farthest remote from the receptacle5 the tube 9 is closed through the medium of a suitable disk 15, whichdisk 15 is of a peculiar construction, which construction will berecited more in detail, fashioned as a jet for the discharge end ofthetube 9. i

The disk 15 has the body portion thereof bow-ed outwardly as at 16-1 6to provide discharge openings 171'Z at spaced points on the upperperiphery of the disk 15, while the disk is also pressed outwardly orbulged asat 16-16 to provide discharge openings 1717 atspaced points onthe lower periphery of the disk 15 to provide lower discharge openingsfor the tube 9. v The pressed out portions 1616 and 16-16 taperinwardlyfrom the outer periphery of the disk 15 .to merge into one anothersubstantially at a center point in the disk 15. r

An elongated, longitudinally extending partition member 18 extendstransversely of 1m the tube 9, and said partition member 18 terminatesat its opposite end inwardly from the adjacent end of the tube 9 for apurpose to be hereinafter more clearly set forth.

This partition member 18 divides the tube 9 into an upper air passage 19and a lower fluid passage 20. The partition member 18 at one endterminates in a rearwardly and upwardly inclined extension 18 to providea baflie plate or deflector at the entrance end of the tube 9, or atthat end of the tube to which the bulb 14: is attached, and thisdeflector plate 18 extends above the end of the tube 12 so thatobviously when the bulb 14 has been depressed then expanded a part ofthe air forced therefrom into the tube 9 will be deflected downwardly bythe deflector baffie plate 18 into the tube 12 to the bottom of thereceptacle 5, and the air discharged from the tube 12 will act as anagitator to disturb whatever sediment of the liquid in the container 5that may have settled on the bottom of the container, thus keeping thematerial in the container 5continually agitated.

At its opposite end, the partition member 18 is spaced above andrearwardly with respect to a transversely extending vertical partition21to provide for the fluid passage 20 an outlet 22 inwardly of the tubeand rearwardly of the jet or disk 15.

Obviously then certain of the air through the tube'9 which has not beendeflected 'by the plate 18 will continue through the passage 19, and asit'passes'over the opening 22 will set up a suction action through thepassage 20 and tube 10 for drawing the liquid in the receptacle 5 upthrough the tube 10 and the passage 18 through the opening 22 to minglev with the air passing'over said opening 22 and thus be dischargedthrough the upper and lower jet openings 17 and 17 respectively to bedischarged from the tube 9 in a fine thin spray or vapor, there beingtwo of the sprays directed upwardly and two of the sprays directeddownwardly as is obviousfrom the position of the openings 17 and 17respectively.

This discharge of the solution or liquid in the container 5 in oppositedirections and in spray form greatly enhances an atomizer of this typerendering the same particularly adapted for-use in the treatment ofwidely prevalent diseases of the mucous membrane of the mouth.

It is believed that from the foregoing description, taken in connectionwith the accompanying drawing a clear understanding of the construction,operation, utility and ad vantages of an atomizer of this nature will behad by those skilled in this art, and a more detailed descriptionthereof is therefore deemed unnecessary.

Even though I have herein shown and described the preferred embodimentof my in vention, it is to be understood that the same is susceptible ofchanges fully comprehended by the spirit of the invention as hereindescribed, and the scope of the appended claims.

Having thus described'my invention, what I claim as new is:

1. Atomizer comprising a container and an having an opening at the endadjacent said discharge aperture and having an angularly disposedportion adjacent its other end ex tending into said container, saidtube. having a lateralbranch, opening in the bottom wall thereofadjacent the angularly disposed por-, tion of said inner conduit, andextending'into said container, the said partition extending beyond saidangularly disposed portion and over the point of communication of saidlateral branch with said tube, forming abaflie directed toward said bulbfor deflecting a part of the air jet created by said bulb through saidlateral branch into said container.

2. Atomizer comprising a container and an atomizingnozzle including atube mounted on said container having a bulb at one end and dischargeapertures at the other, a partition extending longitudinally within saidtube defining an inner conduit terminating at both ends short of theends of said tube, having an opening at the end adjacentsaid dischargeapertures, and having an angularly disposed portion adjacent its otherend extending into said container, said tube having a lateral branchopening in the bottom wall thereof adjacent the angularly disposedportion of said inner conduit and extending into saidcontainer, thedischarge end of said tube being closed centrally with the dischargeapertures opening peripherally, and 'theadjacent end of said innerconduit having its opening defined by a walloccluding its lower half andterminating in a transverse edge.

In testimony whereof I afiix my signature.
